I'm kinda torn between the classic cowl hood (I wouldn't go bigger than 3", personally) and a 2.5" Stormin Norman/Mach 1 hood. Cervini's would be the way to go in either case, but they don't come cheap. Wait for a big Ford event within driving distance of ya' (World Ford Challenge always has some great deals in the vendor alley), borrow a truck from a friend/relative, and pick one up then - even after gas money, you'll still likely come out a good deal cheaper than ordering straight-up at any other time of the year. That, or keep your eyes peeled for anyone selling one off on a Craigslist ad near you...
